MRI of osteoporosis-related anatomical locations are
generally acquired with a surface coil in order to obtain sufficient
sensitivity and resolution for quantification of the trabeculae, however these
coils introduces intensity inhomogeneities which affect the analysis of the
trabecular bone structure. This work demonstrates the benefits of intensity
normalization based coil correction for MRI data acquired with phased array
coils in trabecular bone structure analysis compared to low-pass filtering.
